Matsumoto Kiyonaga's premonition was bound to be correct.
After all, that was hinted and guided by Tang Ze. It can be said that Tang Ze threw out clues and worked backwards after knowing the answer.
However, Tang Ze still patiently cooperated with Matsumoto Kiyonaga, intending to finish the show.
The reason why he deliberately guided Matsumoto Kiyonaga to think of the key to the secret code was naturally to divert the attention from him.
He discovered the clues to the Big Dipper and luckily saved Matsumoto Kiyonaga who was trapped in the Beika Forest, which was already conspicuous enough.
As for the remaining clues, it would be more appropriate to let Matsumoto Kiyonaga take the lead in discovering them, which would also make his actions of going to the Beika Forest late at night seem more reasonable.
Otherwise, if you already know that "Qixi·Jing" is the code to find the criminal, why would you still go to the Beihua Forest to look at the starry sky to confirm whether the constellations are consistent with the position of the deceased?
After the two got a clue, they drove towards the direction of the Scientific Research Institute facing the sunrise. This was his base camp. As long as Matsumoto Kiyonaga hid in the back seat and did not show his face, Karasawa+, as the leader, could easily send away the staff on duty.
After taking the elevator from the underground parking lot directly to Karasawa's office, Matsumoto Kiyonaga did not even mention resting, but urged him to investigate whether anything had happened in Tokyo and Kyoto on Tanabata Festival in previous years.
With Tang Ze, who knew the answer, he easily found out that a fire had occurred in a hotel two years ago.
"The deceased was Nanako Motoue. The investigation file showed that the hotel's emergency exit was blocked and the elevator was overloaded. Nanako Motoue voluntarily got out of the elevator, and this result is officially recognized."
Tang Ze said: "If we can confirm that the six victims all stayed at this hotel when the fire broke out two years ago, then the culprit may be someone related to Motogami Nanako.
The other party may have thought that these victims forced Nanako Motokami to get off the elevator, so they chose revenge.
Everything fits together. The vertical line on the back of the mahjong tile left by the criminal at the crime scene probably represents the elevator door.
The different red areas on the front of the seven cakes may represent the positions where the victims were standing in the elevator at the time.
The Greek letters on the back of the mahjong tiles are the capital letters of each star. I have confirmed that the places chosen by the criminal are the North Star and the Big Dipper. It is definitely correct.
Perhaps it was because Nanako Motogami liked the Big Dipper that the criminal chose this method to commit the crime."
"Well, that's a very reasonable guess!" Matsumoto Kiyonaga said excitedly, "Now all we have to do is verify and confirm this information as soon as possible!"
"This is Fumimaro Ayanokouji in Kyoto. It's half past five now. It's a bit early for me to call him."
Tang Ze checked the time and said, "Besides, it's so early, I'm afraid the hotel won't be open yet. We should just rest for a while."
"Hmm... well, I've been mostly sleeping these days since I was imprisoned, so I'm not sleepy. You've been investigating the case all day yesterday, and you were still worrying about it in the middle of the night. You must be exhausted after tossing and turning all night."
After hearing what Tang Ze said, Matsumoto Kiyonaga thought about it and felt that there was really no time to rush, so he nodded and said, "Let's rest for an hour first."
"Okay, I'll text someone to bring us breakfast."
After sending a text message to Koshimizu Nanatsuki, Tang Ze and the other man closed their eyes and rested on the sofa. Fortunately, when he was waiting at the house of Honjo yesterday afternoon, there was no movement from that house, which allowed Tang Ze to rest for half a day.
Otherwise, even Tang Ze would be a little tired after traveling all the way and staying up late.
As for now, an hour's rest is enough for him to recover.
It was a pity for Ayanokouji Fumimaro who was in Kyoto. He was woken up by two police inspectors, Karasawa and Matsumoto Kiyonaga, early in the morning while he was still asleep.
However, after hearing what Karasawa said, Ayanokouji Fumimaro immediately became serious. After repeatedly assuring himself that he would keep the secret, he immediately went to the hotel where the fire broke out that year to verify it.
"Everything is just as you deduced, Detective Karasawa!" Matsumoto Kiyonaga's expression brightened upon hearing this: "So the suspects are the deceased's brother Motogami Kazuki and her lover Mizutani Kousuke. We must find these two suspects and apprehend them as soon as possible!
The murderer can be identified later, but no more victims will be allowed to appear!"
"I'll lead the team to capture him myself."
Karasawa pretended to be in deep thought and said, "According to the investigation, Mizutani Kosuke lives in Mitaka City, while Motogami Kazuki lives in Chiba Prefecture.
But considering that today is Nanako Motogami's death anniversary, perhaps Kousuke Mizutani will go to the Motogami family or the cemetery to pay his respects.
I plan to have Takagi and Sato Miwako go to Mitaka City to find Mizutani Kosuke, and I will go to Chiba Prefecture myself."
"Yes, but first you have to make sure they haven't been swapped."
Matsumoto Kiyonaga warned, "Since they were able to disguise themselves as me, there's no guarantee that other members wouldn't be able to sneak in by disguising themselves as me."
"Don't worry, I have taken this into consideration, so I arranged for them to go."
Tang Ze smiled and said, "They are a couple and they work together. Normally, they wouldn't be chosen for disguises because they would be easily exposed.
Moreover, they and I are old partners and are very familiar with each other. After telling them the truth, both sides can prove to each other that the other party has not been replaced."
"Well, I'm glad you thought about it."
Matsumoto Kiyonaga said with a serious expression: "But more importantly, we must keep it secret before the operation. If they encounter the suspect, we must immediately ask them to bring the criminal back.
We still don't know the details of the organization lurking in the shadows, and we don't know what they'll do. We must be extremely cautious and remember to remind them to stay safe."
"I will."
